Mar proclaims James as "their lawful sovereign"…

Mar proclaims James as "their lawful sovereign" on September 6 and raises the old Scottish standard.

Mar's proclamation brings in an alliance of clans and northern Lowlanders, and they quickly overrun many parts of the Highlands.

Mar's Jacobites capture Perth on September 14 without opposition.

His army grows to around eight thousand men.

A force of fewer than two thousand men under the Duke of Argyll holds the Stirling plain for the government and Mar indecisively keeps his forces in Perth, waiting for the Earl of Seaforth to arrive with a body of northern clans.

Seaforth is delayed by attacks from other clans loyal to the government.

Planned risings in Wales, Devon and Cornwall are forestalled by the government arresting the local Jacobites.
